This easy coffee milk pudding recipe uses only three ingredients (sugar, coffee milk, and gelatin) and no eggs or butter, and can be made in a single container. Since it requires no oven or steamer, and can be completed using only a microwave and refrigerator, it's perfect for beginners. First, easily make caramel in the microwave and spread it in the container, letting it harden at room temperature. Next, heat the coffee milk and softened gelatin in the microwave until dissolved, then slowly pour it over the caramel. Chill in the refrigerator for at least three hours to set, and you'll have a smooth, wobbly pudding. The gentle sweetness of the coffee milk and the slight bitterness of the caramel are a perfect match, making it ideal for a home café experience or as a dessert after a meal.
